      Protect your part assemblies with a smooth spacer

      The spacers, which are commonly called “sockets” play an essential role in mechanics and industrial assembly. They guarantee the precise positioning of the components, thus reducing the risk of deformation or unwanted movement. These small parts, often overlooked, can have a significant impact on the overall performance of a mechanism.

      La smooth socket, smooth spacer or compression socket, often underestimated, offers remarkable robustness.

      Its cylindrical structure not only provides structural stability, but it is also resistant to mechanical stress.

      The smooth spacer is specially designed to absorb significant loads and maintain the integrity of the parts of an assembly. Its sturdy design makes it an essential choice for projects requiring increased resistance to compression forces.

      What is a smooth spacer or compression socket?

      Les smooth compression spacers, are cylindrical fastening solutions designed to protect assemblies of mechanical and plastic parts against compression forces.

      They are specially designed to be used after the moulding or overmoulding of plastic parts in order to prevent deformation.

      Thanks to their solid and durable structure, these spacers make it possible to compensate for dimensional variations that occur during thermal shocks or the mechanical forces of an assembly.

      In short, a smooth cylindrical spacer offers a reliable and effective solution to ensure the stability and durability of metal and plastic part assemblies, while maintaining their integrity.

      These spacers are found in industrial fields including the automotive industry and particularly in intake manifolds or air conditioning connections.

      How are LGC smooth spacers made?

      There are two different methods for creating a smooth spacer.

      From pin to smooth spacer

      It is possible to start from a solid material that has been machined in order to arrive at a shape of pin. In this specific case, it is necessary to drill a pin to make it hollow, this is called a bore, which complicates the process both financially and technically and environmentally.

      From the tube to the smooth spacer

      In a second case, it is possible to make a compression spacer or socket starting from a tube.

      The use of a tube is highly recommended because it perfectly meets all criteria (price, quality and also carbon footprint).

      That's the technique we use at LGC.

      The first step in manufacturing a spacer is cutting the raw material.

      The raw material is in the form of long, hollow tubes. The material and the diameter depend on the desired final part.

      The tube enters a machine which cuts it to the desired length.

      The part can be further machined with specialized machines.

      For example, chamfers may be required or material finishes may be applied to your spacers.

      The part then goes through a grinding stage.

      A roller presses the parts against a grinding wheel rotating at high speed. It is the wheel that, by abrasion, will modify the diameter of the part to reach tolerances of a few microns (~5-6 μm).

      What are the advantages of a smooth spacer?

      • Absorption of charges: thesmooth spacer / compression sleeve is designed to absorb and distribute loads effectively, reducing pressure on adjacent components. This ensures an even distribution of stresses, preventing deformations and maintaining the integrity of the whole.
      • Stability: by maintaining structural stability, the smooth spacer/compression bushing helps prevent deformations and potential failures. It reinforces the overall solidity of the assembly, thus ensuring reliable performance over time.
      • Vibration reduction: thanks to its ability to absorb vibrations, the smooth spacer/compression socket improves the comfort of using the assembly. This is especially beneficial in applications where excessive vibration can cause premature component wear.
      • Shock absorption: The smooth spacers/compression sleeves act as shock absorbers, minimizing shocks and impacts. This protects fragile components from potential damage, extending the useful life of the set.
      • Ease of installation: Featuring a practical design, the smooth spacers/compression sleeves are easy to install. This ease of installation allows for quick and efficient assembly, reducing downtime during production or maintenance.
      • Material compatibility: Smooth spacers/compression sleeves are versatile and compatible with various materials, such as metal, plastic, or composites. This adaptability makes them ideal for a variety of industrial applications.
      • Dimensional accuracy: By maintaining precise alignment between components, smooth spacers/compression sleeves contribute to maintaining the dimensional accuracy of the assembly. This is crucial in areas where tight tolerances are required.
